RAN Sharing Type Detection via PLMN and Band Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack defined interfaces and procedures for handling the intersection of Radio Access Network (RAN) sharing and RAN slice management, leading to challenges in automatically detecting and managing RAN sharing types within computer networking systems.
Innovation Solution
A computing system analyzes message profiles containing Public Land Mobile Network (PLMN) identifiers and operating bands to automatically detect and determine the type of RAN sharing, configuring network devices and provisioning network slices accordingly, enabling the management of network slices based on the determined sharing type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual detection and configuration methods are used for RAN sharing types, then system complexity is reduced, but automation extent and productivity deteriorate
Solution Approach 1:
The system automatically detects RAN sharing types by analyzing PLMN identifiers and operating bands in network messages without requiring manual configuration or intervention. The computing system self-services by autonomously determining whether MORAN or MOCN sharing is in use based on the presence of multiple PLMN identifiers and their associated operating bands.
Solution Approach 2:
The system performs preliminary detection of RAN sharing types during network slice provisioning before actual network operations begin. By analyzing message profiles containing PLMN identifiers and operating bands in advance, the system prepares the appropriate network configuration and forwarding rules beforehand, avoiding the need for manual detection later.
2Productivity
If manual configuration of network slices is used, then measurement precision is maintained, but productivity and time consumption deteriorate
Solution Approach 1:
The system automatically provisions network slices by detecting RAN sharing types and configuring appropriate forwarding rules without manual intervention. The computing system self-services the entire process from detection to configuration, significantly reducing the time required compared to manual methods.
Solution Approach 2:
The system detects RAN sharing types and prepares network slice configurations in advance during the message reception phase. By performing the detection and configuration preparation before actual network operations, the system eliminates time-consuming manual configuration steps during critical network operations.
3Adaptability or versatility
If RAN sharing detection is not implemented, then device complexity is reduced, but adaptability to different sharing arrangements deteriorates
Solution Approach 1:
The computing system implements a universal detection mechanism that automatically identifies both MORAN (Multi-Operator RAN) and MOCN (Multi-Operator Core Network) sharing types using the same analytical approach. By examining PLMN identifiers and operating bands, the system adapts to different RAN sharing arrangements without requiring separate detection systems for each type.
Solution Approach 2:
The system detects different RAN sharing types by analyzing changes in key parameters: the presence of multiple PLMN identifiers and their associated operating bands. When multiple PLMN identifiers with different operating bands are detected, the system identifies MORAN sharing; when multiple PLMN identifiers share the same operating bands, it identifies MOCN sharing.

AI summary
Techniques are described for determine a type of Radio Access Network (RAN) sharing employed within a network. In one example, a computing system receives a message for implementing a network slice of a RAN comprising a profile including a first Public Land Mobile Network (PLMN) identifier for the RAN and a first operating bands value. Based on determining that another RAN slice subnet is provisioned within the RAN with a second PLMN identifier and the first operating bands value, the computing system determines a RAN sharing type is Multi-Operator Core Network (MOCN). Based on determining that no RAN slice subnet is provisioned within the RAN with the second PLMN identifier and the first operating bands value, the computing system determines the RAN sharing type is Multi-Operator RAN (MORAN). The computing system forwards network traffic for subscriber devices in accordance with the determined RAN sharing type.
